iTech Solutions - for all of your IBM i System needs
For IBM i shops, IBM’s POWER9 scale-out family consists of three main server models. To say these servers can “scale-out” is a massive understatement. At the end of the day we could talk about the enterprise POWER9 family all day but the large majority of IBM i clients are rocking the POWER9 Scale-Out servers. So, I am going to focus my attention in this article on the beautiful, scalable, and rock-solid servers in the POWER9 Scale-out family.
The first thing you need to know is what the model names themselves can tell you. Let’s use S914 as an example. The “S” stands for scale-out, the “9” stands for Power9, the “1” represents the number of sockets (In this case, a single socket), and the “4” which represents the number of rack U’s of physical space the server will take up.
Let’s face it — 2020 hasn’t been the most stellar year for a lot of companies. There is still uncertainty about what will happen COVID-19 and the rest of the year. As a result, some companies choose to hold on to their cash and not make capital purchases. Others have frozen their budgets.
With the end of life for the popular E4D coming on December 31, 2020, many IBM i shops face Extended Support. This support is limited in scope. You can only get a contract for 12 months, and there are no guarantees. IBM Extended Support is better than IBM’s no option, but it’s not the best solution.
If you’re one of these companies struggling to navigate budget constraints in 2020, we have a suggestion: financing. If you’re not worried today, but you want to hold on to your cash, financing is also a fit for you. Do you refresh your hardware on a regular three to four-year cadence? Financing will save you money.
Almost three decades ago, back in 1997, IBM announced the flagship 9337 Disk Array Subsystem, a rack-mount disk unit that offers 1,084 MB to 33.55 GB of DASD for the AS/400 9406 Models B, D, E, and F as well as AS/400 Advanced System Model. Back in the early ’80s, I engaged in a benchmark of the 9337 Disk Subsystem on an enterprise AS/400 against the EMC Symmetric system in Rochester, Minnesota. I also presented RAID technology at a local user group meeting, explaining how to protect the data on the 9337 storage for the AS/400 with RAID 5 technology.
We have come a long way in storage for the Power System. In addition to internal hard disk drives (HDDs), there are Solid State Drives (SSDs), Non-Volatile Memory express (NVMe) drives, and the external IBM FlashSystems with all NVMe storage option. Gone are the days when AS/400 internal storage was usually the first choice in achieving the best performance. This blog discusses various IBM storage options for POWER9 and highlights the cost difference of deploying different storage options on a FlashSystem fiber attached to a POWER9.
